Nice! I use a different test but if you are printing functional tests it is very important to know the finished sizes.
I personally like the Clearance/ tolerance test from Angus (makersmuse) but of late I am using the clearance castle tower only or if I have lots of time the whole castle. It is a good indication of multiple things.
If you are running tolerance tests I think running at the speeds you usually print. I tend to print quite fast and a test at speed is not always the same as one slower.
